Function type which is called once at compile time

[ghost]

Is there anyway we can create a type that function which will be called once at compile time instead of being called every time at runtime?
Thanks for creating such amazing package.

You may use two-step go:generate for generating template output from *.qtpl files before compile time:

• Generate *.qtpl.go files at first step with qtc.
• Generate output file from the generated *.qtpl.go files with go run.
